What it does

On reveal: If an enemy card was revealed here earlier this round, +2 Power to this card.

On reveal happens once, when the card flips.

It costs 3 RAM to play and brings 6 Power to its lane. You get 1 RAM in round 1, 2 in round 2, and so on.

Tech cards bend the rules: more RAM, cheaper cards and patches that weaken the other side.

The site, in 2001

A website of maths-flavoured programming puzzles, meant to be solved with code rather than by hand.

Named after Leonhard Euler, it had 1007 problems by July 2026, with a new one about every week. Each is meant to run in under a minute on a modest computer, and you reach a new level every 25 solved.

In 2001: Colin Hughes created it this year.

Dot-com era, 1999 to 2002. Glossy buttons, big money and a bug called Y2K. Some of these companies were worth billions for about a fortnight.

The Long Tail: The niche, the local and the specialist. Most of the web, really.
